[PATCH] D49517: [WebAssembly] Handle return type conversions in FixFunctionBitcasts pass

[Sam Clegg via Phabricator via llvm-commits]

sbc100 added a comment.

When you say not all types are valid to cast to all others.. how would I know which are valid?  And how would this code fail if they are invalid?  Would llvm bail out during the call to getCastOpcode()?

I ideally we would never actually produce invalid wasm and prefer to fail to compile.. but perhaps that should be done later on during codegen rather that during this pass?
